Abstract
Background and Study Aim. The increasing prevalence of overweight and obesity among university students has emerged as a notable public health concern. This trend is exacerbated by sedentary academic settings and a lack of time-efficient fitness programs. Thus, this study aimed to evaluate the effectiveness of a 6-week progressive running interval training (PRIT) program on endurance and body mass index (BMI) among overweight college students.
Materials and Methods. A total of 30 students (BMI ≥ 25), aged 18–21 years, were randomly assigned to either an experimental group (n = 15), which engaged in thrice-weekly PRIT sessions supplemented with strength-endurance circuits, or a control group (n = 15), which did not participate in any organized physical training. Statistical analyses included paired and independent samples t-tests. The significance threshold was established at p < .05.
Results. Post-test results demonstrated a significant increase in the training group across all assessed variables. Improvements in upper body, lower body, and core endurance were all statistically significant (p < .001). Moreover, a significant decrease in BMI was observed (p < .001). The control group showed minimal changes. These findings confirm the effectiveness of PRIT in improving endurance and reducing BMI within a brief intervention period.
Conclusions. The results confirm the efficacy of the progressive running interval training (PRIT) program in enhancing endurance and reducing BMI over a short intervention period. This supports the integration of scalable, evidence-based interval training into campus wellness programs to improve student health, physical performance, and academic outcomes.
